Miracle on the ocean floor

Harrison Okene spent three days trapped in an air pocket in a sunken ship. Harrison was the ship's cook, and he'd been in the bathroom when the tugboat he worked on had suddenly capsized in bad weather. The vessel sank 30 metres to the seabed, upside down, and Harrison was trapped inside. Days passed, and up on the surface a mission was launched to recover the bodies of the tugboat's crew. Divers descended, but they never expected to find anyone alive. Presenter: India Rakusen Producer: Harry Graham Editor: Munazza Khan Sound design: Joel Cox
